calendar

// 从 2.12.0 开始
moment.updateLocale('en', {
    calendar : Object
});
// 从 2.8.1 至 2.11.2
moment.locale('en', {
    calendar : Object
});

// 废弃于 2.8.1
moment.lang('en', {
    calendar : Object
});

Locale#calendar 应是具有以下格式的字符串。

moment.locale('en', {
    calendar : {
        lastDay : '[Yesterday at] LT',
        sameDay : '[Today at] LT',
        nextDay : '[Tomorrow at] LT',
        lastWeek : '[last] dddd [at] LT',
        nextWeek : 'dddd [at] LT',
        sameElse : 'L'
    }
});

每个 Locale#calendar 键也可以是一个回调函数，具有当前 moment 的范围，且第一个参数是描述现在的 moment。 它应该返回一个格式化字符串。

function callback (now) {
    return '[hoy a la' + ((this.hours() !== 1) ? 's' : '') + '] LT';
}

// From 2.12.0 onward
moment.updateLocale('en', {
    calendar : Object
});
// From 2.8.1 to 2.11.2
moment.locale('en', {
    calendar : Object
});

// Deprecated in 2.8.1
moment.lang('en', {
    calendar : Object
});

Locale#calendar should have the following formatting strings.

moment.locale('en', {
    calendar : {
        lastDay : '[Yesterday at] LT',
        sameDay : '[Today at] LT',
        nextDay : '[Tomorrow at] LT',
        lastWeek : '[last] dddd [at] LT',
        nextWeek : 'dddd [at] LT',
        sameElse : 'L'
    }
});

Each of the Locale#calendar keys can also be a callback function with the scope of the current moment and first argument a moment that depicts now. It should return a formatting string.

function callback (now) {
    return '[hoy a la' + ((this.hours() !== 1) ? 's' : '') + '] LT';
}
